Be it known that I, Earn? G;- Nmnonn, a citizen of the United States;and a resident of the city of Chicago, county of Cook, and StateofIllinois, have invented certain new and useful Improvements in DoorMechanism for Railway-Cars, of'which I do declare the followingv tobeafull, clear, and exact description, reference being had to the accomanyi-ng drawing, forming partof this speci cation. v a i It is customarytoprovide' railway freight cars with sliding doors suspended by trolleyhangers attached to the upper edge of the doors and adapted to travel 11on rails extending above the doorways an secured to the side wall of thecar;

The object of the present invention is to provide improved means forholding the lower edge of the sliding door against pressure from theinside of the car and as well, also, against danger of' being liftedtosuch extent as to displace the trolleys or hangers from the tracks.

The invention consists in-the novel features of improvement hereinafterdescribed, illustrated in the accompanying drawing,

and particularly pointed outin the claims at the end of thisspecification.

In the drawing, Figure 1 is a view in cross section on line 1 of Fig. 2through a portion of the door sill and side wall. of a car, andthroughthe lower portion of a sliding door having my invention applled thereto,one of the retaining brackets being shown in side elevation Fig. 2 is aview in front elevation of the parts shown in Fig. 1. Fig. 3 is a viewin vertical section through,

the lower portion of a steel door embodying my invention.

My invention may be ap'phed 1n connection with wooden doors such as arenow t aj er as j Patented Apr. 2t,-1l915. a nmnta'mta rui 'iag reia.seriarno. 778,890;

. of which-is connected the channel bar 6, this channel bar extendingfrom front to rear of the door. Preferably, the channel bar 6 isprovidedwith. an upstanding member 7 whereby-the bar is attached to thedoor by means of. through bolts or rivets'8 that pass through the lowerportion of the door. Inside the channel bar 6 is preferably placed awedge plate 9 having a beveled end 9* and riveted to the channel bar at10, the pur-' pose of this wedge plate being to insure he tightclosingof the door. l-nto'the channel bar 6 projects the upper, inwardlyextending end 11 of the bracket 12, this ;bracket being suitablyattached, as by through bolts 13, to the side wall of the car beneaththe door sill or plate 14. The upper portion 11 of the guide racket 12is preferably arranged about midwaybetween the top and bottom walls ofthe channel bar 6, and this bracket is preferably reinforced by oneormore strengthening ribs, as shown.

From the oregoing description it will be seen that as the" door is movedback and forth, the guide bracket 12 setting within the channel bar 6serves to resist any out-' member or wall of the channel bar willprevent any excess lifting of the door to such extent as would endangerthe slipping of the trolley wheels or hangers from the overhead Ck- Thechannel bar 6 performs the f -=furthen function of protecting the loweredge of the door and of guarding to a considerable extent the open spacebetween the.

bottom of thedqfdrand the sill 14. Thus,

I fonexamplefi'f the door were not provided-f with the channel bar 6,any rain runnin down the outer face of the door might be blown aroundthe lower edge and'into the" car, whereas thechannel bar not only." ro-jtects the lower edge of'the car doorj om the water but also serves toprevent raing snow, or the like, from being blown into the openingbetween the bottom edge of th door and the door sill 1 1.

The wedge plate 9 within the channel bar 6 serves to force the doorinwardly toward the body of the car and thus vinsure'the door i openingbeing tightly closed. The wedge. plate 9'is placed vat such a positionwithin the channel barthat as the door is moved .to approximately closedposition, the inner hereinbefore described.

' form the channel 6 within which is secured thewedge plate 9, as'in theconstruction Obviously, when the'steel door is provided with a channelbar Bfat its'lower edge, such channel bar will cooperate with aretaining bracket or brackets, as in the construction hereinbeforedescribed, to hold the lower portion of the door against displacement.

-;In the drawings, I'have shown only a.

single retaining bracket 12, but obviously, any desired number ofretaining brackets ,.may be employed, depending upon the length of thedoor. Manifestly, the precise details above set forth may be varied;that is to say, the exact shape of the channel bar may be varied and theshape of the retaining bracket or retaining member may also be' modifiedwithout departing from the spirit of the invention.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent, 1s

1. In a railway freight car, the comb1nation with a sliding door, of anoutwardly facing channel bar secured to the bottom of said door andcovering the lower edge thcreof, said channel bar having formed integralwith its upper member a vertical flange secured to the outer face of thedoor, and a retaining bracket secured "to the car body and having anupwardly and forwardly extendin part projecting within said channel bar,su listantially as described.

2. In a railway freight car,'.thc combina- I tion with a sliding door,of an outwardly facing channel .barsecured to the bottom of said doorand covering the lower edge thereof, said channel. bar having formedintegral with its upper member a vertical flange sccured to the outerface of the door, a retaining bracket secured to the car body and havingan upwardly and inwardly extending part'projecting within said channelbar and width of the horizontal members of said channel bar,substantially as described.
